Hi Christophe,

Thanks.
column_stack() works correctly.

 Hi Magician,
 
 Since Paraview 4.2, you have to use column_stack instead of hstack to
 create a multi-component field. See this thread

[Paraview] vtk.vtkPoints.SetData()

2015-04-27 Thread Magician 
Hi all,


I’m going to generate pointclouds from CSV with Programmable Filter.


On ParaView 4.1 or older, the script works:

from paraview.vtk.dataset_adapter import numpyTovtkDataArray as da
from paraview.vtk.dataset_adapter import vtkDataArrayToVTKArray as va

pdi = self.GetInput()

X = va(pdi.GetRowData().GetArray('x'))
Y = va(pdi.GetRowData().GetArray('y'))
Z = va(pdi.GetRowData().GetArray('z'))

pts = vtk.vtkPoints()
pts.SetData(da(hstack((X, Y, Z)), 'Points’))


But on 4.2 or newer, the script isn’t work:

from paraview.vtk.numpy_interface.dataset_adapter import 
numpyTovtkDataArray as da
from paraview.vtk.numpy_interface.dataset_adapter import 
vtkDataArrayToVTKArray as va

pdi = self.GetInput()

X = va(pdi.GetRowData().GetArray('x'))
Y = va(pdi.GetRowData().GetArray('y'))
Z = va(pdi.GetRowData().GetArray('z'))

pts = vtk.vtkPoints()
pts.SetData(da(hstack((X, Y, Z)), 'Points’))


The error message is as follows:

ERROR: In 
/Users/kitware/Dashboards/MyTests/NightlyMaster/ParaViewSuperbuild-Release/paraview/src/paraview/VTK/Common/Core/vtkPoints.cxx,
 line 193
vtkPoints (0x1199f3a60): Number of components is different...can't set data


How can I use SetData() method on latest ParaView?
